The legislation includes a "minibus" of three full-year appropriations bills, including a full funding of Supplemental Nutrition Assistance Program, or SNAP, benefits through the end of next September, and keeps much of the government open on a short-term basis through Jan. 30.

But in a major concession for Democrats, the deal does not include an extension of enhanced subsidies under Obamacare, or the Affordable Care Act, after Republicans held firm against extending those funds beyond this year. That means more than 20 million Americans could see their premiums spike next year.
